  • sealing portion 23b can be adapted to the sealing portion 24b of boot 24 substantially in the same manner.
  • the present invention can be adapted to a disc brake assembly of the pin slide type wherein the support pin is fixed to the caliper member and slidably inserted into an axial bore in the stationary support member for slidable support of the caliper member.
